Abstract

Reports on the evaluation of a set of commercial PC‐security products. Argues how, and why, this analysis differs from the kind of security evaluation described in the IT security evaluation criteria published recently by some national security agencies. Draws on an in‐depth examination down to the hardware level, based on the actual executable code and covers even attack scenarios where the attacker can manipulate the hardware of the PC. Summarizes the major findings, pointing out some frequent design faults in PC‐security systems.

Abstract

This chapter provides a comprehensive review of research and developments relating to the use of Web 2.0 technologies in education. As opposed to early educational uses of the Internet involving publication of static information on web pages, Web 2.0 tools offer a host of opportunities for educators to provide more interactive, collaborative, and creative online learning experiences for students. The chapter starts by defining Web 2.0 tools in terms of their ability to facilitate online creation, editing, and sharing of web content. A typology of Web 2.0 technologies is presented to illustrate the wide variety of tools at teachers’ disposal. Educational uses of Web 2.0 technologies such as wikis, blogs, and microblogging are explored, in order to showcase the variety of designs that can be utilized. Based on a review of the research literature the educational benefits of using Web 2.0 technologies are outlined, including their ability to facilitate communication, collaborative knowledge building, student-centered activity, and vicarious learning. Similarly, issues surrounding the use of Web 2.0 tools are distilled from the literature and discussed, such as the possibility of technical problems, collaboration difficulties, and plagiarism. Two case studies involving the use Web 2.0 tools to support personalized learning and small group collaboration are detailed to exemplify design possibilities in greater detail. Finally, design recommendations for learning and teaching using Web 2.0 are presented, again based on findings from the research literature.

Abstract

Purpose

This study aims to better understand the relationship between peer feedback in the context of online collaborative note-taking and how comments impacted student performance and understanding.

Design/methodology/approach

This one sample investigation was of graduate students participating in an academic writing class working collaboratively online. Data was gathered on student feedback during note-taking activity to test for its effects on student performance and understanding.

Findings

The use of peer comments in online note-taking was found to impact student quiz scores and academic writing skills positively. However, no significance was found between comments and the completeness of their notes taken, suggesting its limits to promote deeper understanding.

Research limitations/implications

The level and detail about the comments made and how accurately they recall the important details from the video lectures is not known. The average number of comments made weekly by each group was also low.

Practical implications

Designers and teachers using online collaborative activities could benefit by understanding the nature in which peer comments can enhance student learning, bearing in mind the need for explicit guidance in how to comment and at what level of knowledge their comments should target.

Social implications

Online collaboration, peer editing and commenting is widely used by educators and the public. A better understanding of how these elements operate might improve the quality of knowledge artefacts such as academic writing and research notes.

Originality/value

Existing literature focuses mainly on peer feedback on writing or other artefacts; this paper seeks to find out more about the impact of comments in particular on collaborative note-taking.

Abstract

Purpose

The purpose of this paper is to systematically review and assess the current status of research on supply chain sustainability from a network structural perspective and provide an organising framework for future scholarship in this area.

Design/methodology/approach

By adopting an evidence-based approach, this study conducts a systematic review of 73 articles from 18 peer-reviewed journals published between 2000 and 2020.

Findings

Adopting a social network analysis approach, the review identifies specific node-level (i.e. degree centrality, closeness centrality and betweenness centrality) and network-level (i.e. network density, network sub-groups and network diversity) structural properties that play a role in supply chain sustainability. The results reveal that structural properties determine the extent of perception of sustainability risks, the diffusion of sustainability targets, introduction of sustainable innovations, development of sustainability capabilities, adoption of sustainability initiatives and the monitoring of sustainability performance throughout the supply chain.

Originality/value

By distinguishing between supply network and sustainable supply network types, this study extends the existing understandings of the role of network connectivity patterns in supply chain sustainability through synthesising and evaluating the extant literature. This study further clarifies the role of these network structural properties in supply chain sustainability by describing their impact on a set of sustainable supply chain management practices through which firms achieve sustainability goals across their supply chains.

Abstract

Purpose

This study examines whether employees' perceptions of intraorganizational competition, defined as beliefs that the organization evaluates their performance in comparison with others, result in lower supervisor ratings of their conscientiousness if the employees, particularly those with proactive personalities, respond to the resource-draining, competitive work situation with knowledge hiding behavior.

Design/methodology/approach

Multisource data were collected from employees and supervisors in different industries at three points in time. The research hypotheses were tested with hierarchical multiple regression analysis, in combination with PROCESS macro-based bootstrapping, to assess mediation and moderated mediation.

Findings

Beliefs about highly competitive organizational climates are counterproductive, in that they lead employees to conceal knowledge intentionally from other organizational members. This mediating role of knowledge concealment is particularly prominent among employees with a strong desire to take the initiative to protect themselves against the hardships created by a climate of internal competition.

Research limitations/implications

The research design does not allow for formal tests of causality.

Practical implications

For human resource managers, this research pinpoints self-protective knowledge hiding as a key, detrimental mechanism. It imposes dual harms: employees feel threatened by the strict performance-oriented climate, and their defensive reactions make them appear less conscientious to supervisors. This downward spiral is particularly likely to initiate among employees who exhibit a disposition toward action.

Originality/value

This research investigates novel connections between specific organizational elements and outcomes, by specifying why and when employees' beliefs about performance-oriented organizational climates might backfire, due to their negative behavioral responses, such as purposeful knowledge hiding.

Abstract

Purpose

Social network analysis (SNA) seeks to manage the connections between entities through investigating and understanding behaviours and relationships. This study demonstrates the increasing relevance of social network approaches to solving contemporary and looming operations management (OM) and supply chain management (SCM) problems; including the coordination operations challenges raised by increased connectivity.

Design/methodology/approach

The systematic literature review approach adopted here examines 63 papers in OM and SCM published between 2000 and 2019. To-date OM reviews on SNA have focussed on discussing archetypal supply chains, what differentiates this study is the focus on how value was created in other forms of chains and operations.

Findings

This study reveals that current SNA adoption in OM is dominated by a manufacturing style focus on linear, sequential value creation, with a resulting focus only on sequential interdependence. SNA studies on reciprocally co-ordinated value creation (e.g. many service and network operations) are shown to have been neglected and are linked to a new agenda on contemporary management issues.

Research limitations/implications

Beyond encouraging the use of SNA, this study seeks to re-orient SNA approaches towards how contemporary services and networks create value.

Originality/value

Through adopting a unique combination of approaches and frameworks, this study challenges extant work to offer a substantially revised agenda for SNA use in Operations and Supply Chain Management.

Abstract

Purpose

This study addresses how and when the experience of family-induced work strain might steer employees away from efforts to promote innovative ideas. In particular, it proposes a mediating role of role ambiguity and moderating roles of two coworker resources (goal congruence and goodwill trust) in this process.

Design/methodology/approach

The research hypotheses are tested with data obtained from a survey administered among employees who work in a professional services organization.

Findings

An important explanatory mechanism that links family interference with work to diminished championing efforts is that employees hold beliefs that their job roles are unclear. The extent to which employees share work-related mindsets with coworkers, as well as their belief that coworkers are trustworthy, attenuate this harmful effect.

Practical implications

For HR managers, the study shows a clear danger that threatens employees who feel drained by significant family demands: The negative situation may escalate into work-related complacency (diminished championing), which then may generate even more hardships. As it also reveals though, employees can leverage high-quality coworker relationships to contain this danger.

Originality/value

This study adds to HR management research by investigating the role of negative spillovers from family to work in predicting idea championing, as explained by negative beliefs about job-related information deficiencies but buffered by high-quality coworker relationships.

Abstract

Purpose

Deep learning (DL) technologies assist manufacturers to manage their business operations. This research aims to present state-of-the-art insights on the trends and ways forward for DL applications in manufacturing operations.

Design/methodology/approach

Using bibliometric analysis and the SPAR-4-SLR protocol, this research conducts a systematic literature review to present a scientific mapping of top-tier research on DL applications in manufacturing operations.

Findings

This research discovers and delivers key insights on six knowledge clusters pertaining to DL applications in manufacturing operations: automated system modelling, intelligent fault diagnosis, forecasting, sustainable manufacturing, environmental management, and intelligent scheduling.

Research limitations/implications

This research establishes the important roles of DL in manufacturing operations. However, these insights were derived from top-tier journals only. Therefore, this research does not discount the possibility of the availability of additional insights in alternative outlets, such as conference proceedings, where teasers into emerging and developing concepts may be published.

Originality/value

This research contributes seminal insights into DL applications in manufacturing operations. In this regard, this research is valuable to readers (academic scholars and industry practitioners) interested to gain an understanding of the important roles of DL in manufacturing operations as well as the future of its applications for Industry 4.0, such as Maintenance 4.0, Quality 4.0, Logistics 4.0, Manufacturing 4.0, Sustainability 4.0, and Supply Chain 4.0.

Abstract

Purpose

Increasing interest in PhD processes calls for valid and reliable survey instruments that cover key aspects of the PhD experience. Based on recent research, existing questionnaires and interviews with PhD students, the Quality in PhD Processes Questionnaire (QPPQ) was developed to cover a range of influential factors such as perceptions of the research environment and psychological well-being. This paper aims at validating the QPPQ for measuring quality in PhD processes.

Design/methodology/approach

This study assesses the validity of the QPPQ’s scales with special attention to factorial, convergent and discriminatory validity. Six scales were developed based on exploratory and confirmatory factor analyses applied to 23 items in a sample of 1,670 PhD students representing various academic disciplines.

Findings

Results were promising concerning the scales’ psychometric properties and indicators of validity.

Originality/value

The QPPQ offers itself as a theoretically grounded and thoroughly tested instrument for the purposes of evaluating and developing PhD programs at a local level or for researching PhD processes in general.

Abstract

Purpose

Doctoral education (DE) is central to the development and application of operations management (OM) thinking. The European Doctoral Educational Network (EDEN) seminar on research methodology in OM is a structured initiative developed in 1999 by European Operations Management Association (EurOMA) and European Institute for Advanced Studies in Management (EIASM). This intensive five-day seminar has run annually since and, to date, has engaged 486 students. The purpose of this paper is to ask: what role has the OM EDEN seminar played in the formation and academic career development of doctoral researchers, and how has it contributed to the development of EurOMA as a community of practice?

Design/methodology/approach

The authors developed a retrospective case on the design, launch and growth of the OM EDEN seminar employing two data gathering methods (collecting secondary and archival data, and a survey of four selected seminar participants) and a social network analysis.

Findings

The EDEN seminar is an effective educational intervention in developing doctoral researchers and their subsequent academic careers. The seminar has also contributed to EurOMA as a community of practice, bringing faculty together to teach, write and publish leading edge contributions in research methods for OM.

Research limitations/implications

The case is focused on the OM EDEN seminar only, within which the survey is limited to four of the early participants. While another set of participants might respond differently in detail, the authors’ expectation is that participant perception of the role of the seminar would not change. The paper provides an exemplar for European academic associations to guide how they might explore the formation and academic career development of doctoral candidates within a community of practice.

Practical implications

The seminar merits the ongoing support of EurOMA and EIASM, not just in educating doctoral students but also in bringing faculty together to publish leading edge contributions to the OM domain.

Social implications

The paper draws on the areas of student formation, academic career development and communities of practice to illustrate the role played by the OM EDEN seminar.

Originality/value

This paper is the first description, analysis and reflection on the role played by the OM EDEN seminar.
